70s porn videos - "Hoffman and Sohne"

Mr Hoffman sells books and provides his female customers with nice moments in a room at the back of the shop. The number of female customers grows very rapidly and when Mr Hoffman isn't up th the demand, he calls in his two oldest guys who keep the shop going. Unfortunately his youngest guy is only interested in reading. One day, as he delivers books to one of the customers, the lady teaches him about the pleasures of sex. In order to celebrate this, the dad organises a party and all is well that ends well!
